It is an infection carried by mosquitoes. People get West Nile Virus from the bite of a mosquito that is infected with West Nile Virus. Mosquitoes become infected when they feed on a bird that has the virus in its blood. Once infected the mosquito can spread the virus to humans and other animals.

The Village works with the Cook County Department of Public Health and the Des Plaines Valley Mosquito Abatement District to monitor the virus throughout the regular testing of mosquitoes in the area. Dead birds are also tested for West Nile Virus.

The Des Plaines Mosquito Abatement District treats all street catch basins with larvicide every 7 - 10 days during the mosquito breeding season. The abatement district will also treat catch basins on private property on request. Call 708-447-1765 or visit the website for more information.

The presence of dead crows and blue jays in a community is a sign of possible West Nile Virus in the area. If you find a dead bird, especially a blue jay or crow, please report your sighting to the Cook County Dept. of Public Health at 708-492-2650. Also contact the Des Plaines Valley Mosquito Abatement District at 708-447-1765. Or fill out a dead bird report form. You can also report your sighting or report online.

The chance of being infected with the West Nile Virus is quite small. Less than 1 percent of mosquitoes are infected, and less than 1 percent of the people who are bitten by an infected mosquito become severely ill. People over 50 and those with compromised immune systems are the most susceptible.

Most people infected with West Nile Virus have no symptoms of illness and never become ill. Some people may become ill 3-15 days after being bitten by an infected mosquito. Symptoms may include fever, headache and body aches. More severe symptoms may be a high fever, stiff neck, confusion and muscle weakness.
